  • the present invention relates to a maintenance-free linear annular type connection and to devices comprising at least one such connection, for example optical devices requiring precise adjustments.
  • a link according to the preamble of claim 1 is known from document WO 85/05464 .
  • the ball or spherical connection provides a connection between two elements for rotation about three axes, one of the elements relative to each other.
  • the ball joint comprises a male sphere and a female seat with or without play, but also bearings for small deflections.
  • These ball joints operate by sliding or rolling, interposing balls between the male element and the female element of the connection.
  • This link is very efficient, however it requires a maintenance, in particular lubrication due to greater or lesser friction depending on the load applied to the connection, or to avoid seizing bearings (eg ball).
  • the connection is not operated for a long time, it may seize, by matting or lack of lubrication.
  • the ball joints of the state of the art are relatively complex structure, requires particularly careful manufacturing, since an adjustment between the different elements is required, and therefore have a high manufacturing cost. Moreover, they require regular maintenance, to ensure their behavior over time. Finally, these links are sensitive to external elements.
  • an optical component and actuators for adjusting the angular position of the component relative to the support, it is sought during the angular adjustment performed by means of actuators the optical component does not deform by more than a few tenths of microns.To this, it is necessary that the ball joints do not generate a significant resisting torque on the support, which would transmit the deformation on the optical component.
  • a link having a rod adapted to deform to provide three degrees of freedom in rotation, and a base substantially perpendicular to the rod, the deformation in the direction of the axis of the rod provides a degree of freedom in translation.
  • connection is made in which all the elements are fixed relative to one another and the deformation of the materials is used to obtain the required rotational and translational movements. Since the link is intended to allow movements of small amplitude, it is possible to use the deformability of the material to carry out these movements, without risk of damaging the link, the movements requiring little connection in itself. For this, the materials used to make the connection provides a high elastic limit.
  • the maintenance of the optical component in its support is made isostatic, for example by supports on three points and imperfect links are used which are deformable for small displacements, which can possibly transmit a parasitic torque. , which is not troublesome for the setting.
  • the base comprises a central thinned zone on which is fixed the rod, this zone then being able to deform elastically along the axis of the rod because of its small thickness.
